Last week at WebCamp Zagreb, a conference for developers and designers, a presentation titled "Let your devices talk to each other" explored the potential of IoT, M2M, and decentralization to enable devices to communicate directly on a home network, rather than through cloud-based servers. The presentation highlighted concerns about data privacy in the cloud and proposed using Couchbase Lite for peer-to-peer (P2P) sync on local networks to maintain control over data. Demonstrations included using network protocols like Bonjour and JmDNS for automatic service discovery to facilitate device communication. An experimental project was showcased, employing Java and the JmDNS library to enable devices to automatically sync without credentials, though security remains a concern. The goal is to encourage more secure and efficient device interaction within local networks, inviting feedback and further exploration of enhanced synchronization methods.
